With this memory foam mattress, your entire body is supported in the correct anatomical position, which allows your spine to experience the best natural sleeping posture. The reduction of pressure points, will decrease the need to toss & turn during the night, providing a more restful & undisturbed sleep. Memory foam was originally developed by NASA to relieve pressure build up from the G-force experienced by astronauts during lift off. Now you can not only experience these pressure relieving qualities while you sleep, but also, as memory foam absorbs motion, you will not feel your partners movements, allowing you to sleep more soundly. Each person will be supported independently, ensuring that your partners movements do not disturb you. What is Outlast? The Outlast technology was originally developed for NASA to protect astronauts from temperature fluctuations. Today Outlast brings comfort to the life of millions of people on earth & has been awarded with the prestigious seal of approval " Certified Space Technology™". With Outlast you feel not too hot, not too cold – but just right. Outlast Adaptive Comfort materials will keep you more comfortable by absorbing excess body heat when you create it. Or alternatively releasing it when you need it most. The result: You stay warmer with less bulk & sweat less over a broad range of temperatures & activity levels. Outlast products protect against overheating & reduce chill & shivering after exertion in cold surrounding or during inactivity. Based on your ideal skin temperature the patented Outlast Thermocules absorb excess heat when you overheat. This is returned to your body when your temperature drops. The result: Outlast creates a comfort zone next to your body.
